Specification of Letters Patent.

ltattaited Mar. 10, 191st. Serial No. 729,684.

To all whom it may concern Be it known that I, Janos SCHUMANN, a subjectof the EIIlPGl'OI of Anstria-Hl'lngary, residing at Reindorfgasse 36,Vienna, XlV, in the Province of Lower Austria, Austria- I'lungary, haveinvented certain new and useful Improvements in Door-Hats, of which thefollowing is a specification.

The present invention relates to that kind of door-mat in which tufts offiber or the like, mounted in the shape of flat brushes in a metalfoinidation, are connected to form a mat, and has for its main object toprovide a mat of such kind that the brush tufts are prevented frombecoming loose either in the transverse or in the longitudinaldirection, and. thus are prevented from falling out. For this purposethe foundation frames or bases of the brushes are sleeved over shapedbars, in such a way that the latter pass through the said brushfoundations which fit the cross-section of the bars, said bars extendingthrough correspondingly shaped perforations in the transverse supportingmembers on which the brush foundations are supported againstlongitudinal displacement and twisting.

A further feature of the present invention consists in the particulararrangement by means of which the members are secured and the wholeframe is held together.

Figure 1 is a detail perspective section of a part of my improved mat.Fig. 2 is a dctail transverse section of the same. Fig. 3 1s a detailplan View of the frame. Flg. t

is a detail View of the corner of the mat, the bristles being omitted.Fig. 5 is a detail perspective View of the corner of the mat shown inFig. l, the bristles being shown. Fig. 6 is a detail cross-section onthe line A-B of Fig. l, and Fig. 7 is a detail longitudinal section onthe line CD of Fig. l.

According to the form of the invention shown in Figs. 1, 2 and 3, Iprovide square connecting bars 7, and hollow brush sections (3 havinglower enlarged square portions corresponding to the shape of theconnccting bars. The connecting bars f pass through square openings inthe web c of I shape transverse bars 7 which prevents said bars turning.The upper portions of the hollow brush bars are reduced to receive andclamp the bristles. The opposite top flanges of transverse bars y arenotched at e, the notches being in alinement with th openings in the web:0. The ends of the reduced upper portions of the brush sections fit inthe notches as clearly shown in the drawing, and prevent said brushsections being bent under the pressure produced in the use of the mat.This construction also serves to hold the parts together, so that it isunnecessary to employ rivet or the like.

In the form of the invention shown in F t to 7, I employ two channelirons y 2 placed side by side to form the intermediate transverse bars,while the end bars are formed of a single channel bar y. The upperflanges of the channel irons are formed with notches .2 In these figuresthe brush sections it are of substantially tri angular shape and thecormecting bars are of similar shape. The webs of the transverse barsare formed with triangular openings through which pass the connectingbars f. lVhen the parts are assembled the protruding ends of theconnecting bars are bent over to form eyelets or heads j which serve toretain the parts of the mat together. ltods a (Fig. t) or the like mayextend through the eyelets f" in order to fasten the mat for securityagainst theft. The sides of the mat are formed by U-shape side bars I),the end center portions of which form extensions 7i, which are bentaround the corners of the end transverse bars and receive the ends ofthe outer connecting bars as shown in Figs. 4 and 5. The lower ends ofthe transverse bars 3 are extended as shown at 0 and pass around theside bars Z) and through the outermost notches 2 and under the. upperflanged portions of said bars W as shown at g. By this construction theside bars 6 are embraced at intervals corresponding to the intervalsbetween the several transverse bars, which with the extensions it form asubstantial means of locking the parts together.

I claim 1. A door-mat comprising transverse bars having upper and lowerhorizontal flanges, the upper flanges having notches and theintermediate web portions of said bars having openings in alinement withthe notches in the flanges, hollow brush sections fitting between thewebs of the transverse bars, the upper ends of the said sections fittingin the notches, connecting bars extending through the hollow brushsections and the openings in the webs, and means for fastening theconnecting bars.

2. A door mat comprising transverse bars having upper and lowerhorizontal flanges, the upper flanges having notches and theintermediate web portions of said bars having openings in alinement withthe notches in the flanges, hollow brush sections fitting between thewebs of the transverse bars, the upper ends of the said sections fittingin the notches, connecting bars extending through the hollow brushsections and the openings in the webs, the ends of the connecting barsbeing bent into eyelets to fasten the bars and sections together.

3. A door-mat comprising a series of transverse bars formed with endprojections, said transverse bars having notched flanges, a series oflongitudinal hollow brush sections located between the transverse barsand engaging in the notches, the transverse bars having openings inalinement with the notches, connecting bars extending through the saidhollow brush sections and the openings, means for securing saidconnecting rods in position, side bars against which the ends of thetransverse bars abut, the ends of said side bars being bent around theend transverse bars, and the projections on the ends of the transversebars being bent around the side bars and passed through the end notchesand bent under the flanges of said transverse bars.

4. A mat comprising a series of transverse bars formed with upper andlower flanges, the upper flanges having notches and the said bars havingopenings in alinement with said notches, a series of longitudinal brushsections located between the transverse bars, each section having anenlarged lower porproj ecting tion and an upper reduced portion, thereduced portion fitting in the notches in the flanges, U-shaped sidebars against which the ends of the transverse bars abut, the transversebars having end extensions which extend around the U-shaped side barsandproject through the end notches and are bent under the flanges, theside bars having end portions which arebent around the end transversebars, and means for securing the latter projecting portions.

5. A mat comprising a series of transverse bars having upper and lowerflanges and openings formed intermediate said flanges, the upper flangeshaving notches in alinement with the openings, a series of hollow brushsections interposed between the trans-- verse bars, each of said hollowsections hav ing an enlarged lower portion and an upper reduced portion,the ends of the reduced portions fitting in the notches, connecting barsextending through the hollow brush sections and the openings, means forsecuring the connecting bars in position, side bars against which theend bars abut, said side bars having projecting end portions which arebent around the end transverse bars and engage the ends of certain ofthe connecting bars to bind said side bars in position.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
